Missing Resource Exception

I was using gradle 1.7. Now to support java 11, I have moved to Gradle 6.1.1.

After building the jar, when I run the jar, I get below exception.
Let me tell you, the file “com.ptc.windchill.install.framework.frameworkResource” is present in the jar file which I am executing.

java.util.MissingResourceException: Can’t find resource for bundle com.ptc.windchill.install.framework.frameworkResource_en, key 1
java.util.MissingResourceException: Can’t find resource for bundle com.ptc.windchill.install.framework.frameworkResource_en, key 1
at java.base/java.util.ResourceBundle.getObject(ResourceBundle.java:564)
at java.base/java.util.ResourceBundle.getString(ResourceBundle.java:521)

The build,gradle file is as follows. The “com.ptc.windchill.install.framework.frameworkResource” file is present in InstallerSupport.jar file.

}

task ia_builder(type:Exec) {
workingDir “$projectDir”

//on windows:
commandLine “$install_anywhere_home/build.exe”, “$projectDir/PSM_IA.iap_xml”, ‘-all’

//store the output instead of printing to the console:
standardOutput = new ByteArrayOutputStream()

//extension method stopTomcat.output() can be used to obtain the output:
ext.output = {
return standardOutput.toString()
}
}

Could you please suggest what might be going wrong.

Thanks,
